1 Maximum specifications are measured across a temperature range of
40°C to +130°C (case), a DVDD range of 1.62 V to 1.98 V, and an AVDD range of 2.97 V to 3.63 V.
2 Power dissipation does not include IOVDD power because the current drawn from this supply is dependent on the loads at the digital output pins.
